CARBURETOR-CYLINDER FOR AIR-GAS MACHINES.

SPECIFICATION forming part of Letters Patent'No. 251,329, dated December20, 1881. Application filed September 23, 1881. (N0 model.)

To all whom it may concern:

Be it known that I, WILLIs H. WINN, of the city, county, and State ofNew York, have invented certain Improvements in Oarbureting- Cylindersfor Air-Gas Machines, of which the following is a specification.

This invention relates to that class of apparatus commonly called gasand air carburetors, and in which atmospheric air or like ten- 10 nonefluid is passed through or in contact with volatile liquid hydrocarbonsin order that the air or the like may be charged with the hydrocarbonvapor, and be thereby converted into an illuminating-gas, so called.

1 My said invention relates to the construction of thecarbureting-cylinders of such apparatus; and its object is to provideagainst the packing together of the filling of the cylinders, which inmany cases tends to destroy the efficacy of the operation of theapparatus.

My invention consists in a carbureting-cylinder constructed with threeor more longitudinal compartments for receiving the cottonwaste or otherfilling, and having in each of 2 5 said compartments one or moreforaminated sacks or shells embedded in or surrounded by thecotton-waste orother filling, so as to provide a facile means of escapefor the air or tenuous fluid after the same has. been carbureted by 0passingthroughthefillingsaturatedorcharged with the carbureting-liquid.

The invention also comprises a novel combination of parts, which, bytheir joint action, insure the rapid absorption of the hydrocarbon bythe airorother tenuous fluid passed through the apparatus, the relativelooseness or porosity of the cotton-waste necessary to the continuedefficient operation of the latter in transmitting the hydrocarbon to theair, and the discharge of the carbureted air, so termed, with a rapidityand facility proportioned to the rapidity and facility of itsproduction.

Figure 1 is a central longitudinal sectional view of acarbureting-cylinder constructed ac- 5 cording to my said invention; andFig. 2 is a vertical transverse sectional view, taken in the line as a:of Fig. l; and Fig. 3 is also a transverse sectional view of Fig. 1.

The cylinder is, as its name indicates, of cylindrical form, and has itsshell formed of sheet metal or other suitable material. Its ends areconstituted by spiders B, which may be of cast metal. The arms a of thespider at one end of the cylinder are coincident in position with thoseat the other end of the cylinder, so that longitudinal partitions may berun from the one spider to theother, thereby dividing the cylinder intoa corresponding numberof longitudinal compartments. The number ofcompartmentsin the cylindermaybethree ormore. The ends of the cylinder,moreover, have stretched across them a coarse wire-cloth, the meshes ofwhich should be of such size as to permit the ready passage of airtherethrough and at the same time retain within the cylinder the 0012-ton-waste or other filling.

G are shells or sacks, as they may be termed, formed of wire-cloth orother suitable foraminated material, which are placed lengthwise in thecompartments, and which, in their 0 cross section, have the flattenedform more clearly represented in Figs. 2 and 3. These shells or sacks (3are placed (one or more) in each of the compartments of the cylinder,and are surrounded by the packing of said compartment, as indicated bythe aforesaid Fig.2.

Upon each end of the cylinderis a closed head,

0, between which and the adjacent spider, B, is

a space orchamber, f. The air or tenuous fluid to be carbureted isintroduced through a suitable pipe and stuffing-box at the center oraxis of one of these heads-as, for example, g. In like manner the gas orcarbnreted air or fluid escapes from the opposite end through a similarpipe fitted to the opposite closed head, 0, by 8 asuitable stuffing-box.The filling is primarily placed within the compartments of the cylinderin any usual or suitable manner, and the carbureted liquid, which may beof any of the usual or suitable kinds, may be supplied in due quantityin proportion to the cylinder in any of the ordinary ways. In theoperation of the invention the air passing into the chamber f at one endof the cylinder passes directly into the latter through the fillingcharged with the 5 carbureting material, and thence, when fullycarbureted, into the passages afforded by the shells or sacks (J, andthence outward, to and through the opposite chamber, f, to theoutletpipe g. In this operation theforaminated sacks 109 afford a readymeans for the escape of thecarbureted fluid, and at the same time tendto prevent the packing or wedging of the filling into a too compactmass. When this wedging, however, occurs to some slight extent, as mayfrequently be the case, the cylinder is turned so that the parts of thefilling subjected to compression are brought uppermost and therebyloosened, the compression being transferred to another portion of thefilling. Inasmuch as the cylinder is divided into compartments, as justexplained, and inasmuch as one portion of the filling in eachcompartment must be somewhat'loosened while the other portion in saidcompartment is somewhat compressed, it follows that, taking the entirecontents of the cylinder, there will be practically a uniformity in theaverage density of the filling, and consequently in the surface of thefilling charged with the'carbureting material exposed to the air orfluid to be carbureted.

It is to be understood that the earburetingcylinder is placed upon axialsupports in any appropriate manner.

It is also to be observed that in order to maintain the shells or sacksC in their flattened position they may be provided internally withblocks r, which serve as internal braces, and to which the flattenedsides of the said shells or sacks are securely attached by broad-headednails or other means.

' It is also to be observed that the air or tenuous fluid is to beforced into the cylinder by a pump, as done with air-carburetorshitherto in use.

What I claim as my invention is LA carbnreting cylinder for air-gasmachines constructed with three or more longitudinal compartments andprovided with one or more foraminated shells or sacks, O, embedded in orsurrounded by the cotton-waste or fibrous filling in each compartment,substantially as and for the purpose herein set forth.

2. The combination of the foraminated shells or sacks O with thecylinder constructed with the closed heads 0, foraminated ends 13, andthree or more longitudinal compartments, the shells or sacks 0 beingembedded in the fibrous filling ot the compartments, all substantiallyas and for the purpose herein set forth.
